Mangrove forests

The paper results showed that the more than ten years mangrove community is a stable forest biome. Mangroves from 10 years old should be planned with different species to increase the diversity in species structure and enhance the ability to stabilize the community and withstand changes in coastal habitats.

In the present study "Improving culture conditions for poly(3- hydroxybutyrate-co-3-hydroxyvalerate) production by Bacillus sp. ND153, a bacterium isolated from a mangrove forest in Vietnam", we examined the variations in the compositions of the culture medium to optimize the conditions for PHBV production by Bacillus sp. ND153, a halotolerant bacterium strain isolated from a mangrove forest in Vietnam (Van-Thuoc et al. 2012).

The research article "Polyester production by halophilic and halotolerant bacterial strains obtained from mangrove soil samples located in Northern Vietnam" reports halophilic and halotolerant bacteria isolated from mangrove forests located in Northern Vietnam. Several of these bacteria were able to synthesize polyhydroxyalkanoates (PHAs). PHAs are polyesters stored by microorganisms under the presence of considerable amounts of a carbon source and deficiency of other essential nutrient such as nitrogen or phosphorous.

Mangrove plants play a viral role in protecting the coast, retraining erosion. Especially in areas considered the variable wave conditions, complex dynamic conditions such as the coastal region of Hai Phong city. However, due to various reasons, the development/additional planting of mangrove forests in the coastal area of Hai Phong in some locations has not achieved the desired result.

In this study, we evaluated chemical responses of K. obovata and S. caseolaris through comparisons of the content of metabolites and element ions in leaves of mangrove plants located under different ecological conditions in the Red River delta. In the low salinity area (Thuy Truong), specific leaf areas of K. obovata and S. caseolaris were much lower while the succulent index was higher compared to those in the high salinity area (Kim Trung).

A study on species composition and density of polychaete (Polychaeta) was investigated in mangrove eco-system, Da Loc commune, Hau Loc District, Thanh Hoa province. Samples were collected in April, July, and November, 2010, from cross-sections of Len estuary and mangrove forests. A total of 15 polychaete species, belonging to 11 genera, 9 families and two groups of settlers (Sedentaria) and mobile (Errantia), were recorded in the study areas.

This study was conducted to evaluate carbon accumulation in a mangrove plantation containing one species of Mangrove tree (Kandelia obovata Sheue, Liu & Yong) in Giao Thuy District, Nam Dinh Province, Vietnam. Sixteen sample plots were established and surveyed from December 2008 to May 2010 in order to determine the amount of carbon present in the trees and forest soil.

Until now, data on zoobenthos in the Mekong Delta has been very limited. Prior research has focused mostly on species of economic value such as the Red chut-chut snails. In this research, we investigated species composition and distribution of Brachyura, Bivals and Gastropods in the Tran De Estuary Mangrove forests in Soc Trang province between June and December, 2011, to discover the extent of zoobenthos biodiversity.

Compared to regressions obtained using the traditional logarithmic transformation method, the above regressions had a much better fit. The original biomass data of the sample trees were also used to calculate the proportion of total biomass apportioned to trunk, branches, leaves and roots.

Mô tả ba loài tuyến trùng biển sống tự do thuộc bộ Monhysterida tại rừng ngập mặn ở cửa sông Mê Công, Việt Nam. Loài mới Daptonema brevisetoum sp.nov. về hình thái học tương đối giống loài Daptonema setosum (Butschli, 1874) song khác biệt với loài trên bởi có các lông cứng vòng ngoài cùng trên đầu ngắn hơn (15% so với 50-70% chiều rộng vùng mô ở D. setosum), gai sinh dục cũng ngắn hơn (49Mm so với 61-64 Mm ở loài D. setosum), ngoài ra còn khác biệt bởi các lông dinh dưỡng và lông vùng cổ cũng ngắn hơn...

In Mekong delta, mangrove forest distributes along the coastline of 700 km and it is a homeland for mud crab in tropical areas. The mud crab becomes potential to be alternative species from failed shrimp farming. Particularly, mud crab hatchery has been introduced and operated recently at Bac lieu, Tra vinh, Soc Trang, Ben Tre, Kien giang and Ca mau provinces. However, the survival from zoea stage to crablet stage 1 is low at approximately 5%. In addition, like shrimp rearing, the mud crab hatchery is using antibiotic as major treatment to prevent bacteria and fungi.

The Mekong River Delta in Vietnam can be considered as a large tropical wetland, in which two typical eco-forest wetlands can be distinguished: the inland Melaleuca forest wetlands and the coastal mangrove forest wetlands. Their main functions are the provision of forest commodities, the regulation of the water balance and biodiversity conservation. However as elsewhere under human pressure their existence is under the threat of forest fires and deforestation. Their protection requires the implementation of a multi-level national or sub-national planning policy.
